   Contenti MoldexSynthetic Mold Rubber |
This synthetic mold rubber is as soft and pliable as modeling clay, allowing you to press your model into the rubber without time consuming cutting and pre-forming of the rubber. No rubber residue adheres to models, even after repeated vulcanizations. Molds can be made using the powder separation method: apply Mica Powder to the two mold halves before vulcanization, and the mold just splits apart after vulcanizing. Powder separation eliminates the laborious task of cutting a mold apart. In its vulcanized form, Contenti Moldex is self-lubricating, so that waxes can be cast without using release agents. As a result, wax surfaces are shiny and smooth, which means better metal castings. Moldex is sold by the pound in sheets measuring 15" x 15" x 1/4" thick, and each sheet weighs 3 lbs.
